Guizhou Phosphorus & Chemical (Group) Co., Ltd. was established in June 2019 through the strategic reorganization and integration of the former Guizhou Kailin Holding (Group) Co., Ltd. and Wengfu (Group) Co., Ltd. Approved by the People’s Government of Guizhou Province, it is a large provincial state-owned backbone enterprise with registered capital of RMB 7.58 billion and its headquarters located in Guiyang City. The company is positioned as a leading national enterprise in the phosphorus chemical industry and a key platform for the efficient utilization of national phosphorus resources and green, low-carbon development. Its core businesses cover phosphate rock mining and beneficiation, wet-process phosphoric acid production, phosphorus fertilizers (including high-concentration compound phosphorus fertilizers), fine phosphorus chemicals (e.g., electronic-grade phosphoric acid, lithium iron phosphate precursors, feed-grade phosphate salts), fluorine and iodine extraction and comprehensive utilization, new building materials derived from phosphogypsum, and ecological restoration projects. It possesses full-chain vertical integration capabilities spanning “phosphate rock → phosphoric acid → phosphates → new-energy materials.” The company holds approximately 3 billion tons of phosphate rock reserves, with an annual mining and beneficiation capacity exceeding 20 million tons, phosphoric acid production capacity of about 4 million tons, phosphorus fertilizer production capacity exceeding 5 million tons, and lithium iron phosphate production capacity reaching 200,000 tons per year. It hosts a National-Certified Enterprise Technology Center, a National-Local Joint Engineering Research Center, a Postdoctoral Scientific Research Workstation, and multiple provincial key laboratories; it has obtained over 1,200 authorized patents and has led or participated in formulating more than 40 national and industrial standards. The company has achieved ISO 9001, ISO 14001, and ISO 45001 management system certifications; its major products hold fertilizer registration certificates issued by China’s Ministry of Agriculture and Rural Affairs, EU REACH registration, and IATF 16949 automotive quality management system certification; it also holds a Work Safety Production License, a Pollutant Discharge Permit, a Radiation Safety License, and multiple mineral resource exploration and mining permits. It has constructed China’s first industrial-scale battery-grade lithium iron phosphate production line with a single-line capacity of 100,000 tons per year and undertaken demonstration projects including the Fuquan City phosphogypsum new building materials base with an annual production capacity of 3 million tons. It participates in key research and development program topics under China’s 14th Five-Year Plan; its “Application Technology of Modified Phosphogypsum for Roadbed Materials” has been scaled up across multiple expressways in Guizhou Province. Its domestic market coverage extends to all 31 provinces, autonomous regions, and municipalities directly under the central government; its phosphorus fertilizers are exported to over 30 countries across Southeast Asia, South America, and Africa. Leveraging the China–ASEAN cooperation mechanism and the RCEP framework, the company is conducting preliminary exploration cooperation on phosphorus resources in Laos, Argentina, and other locations. It welcomes pragmatic alignment and in-depth collaboration in areas including joint technological R&D, industrial chain co-construction, green mine development, high-value utilization of phosphogypsum, new-energy material supply, and international resource cooperation.
